With the 2025 Income Tax Return campaign underway, it’s important to remember that the draft return does not include regional tax deductions, so it’s worth reviewing them to maximize your savings. These deductions vary by autonomous community and cover areas such as housing, family, education, health, and sustainable mobility.
What to consider before applying deductions
Regional deductions are usually subject to:
- Income limits.
- Personal or family requirements (age, number of children, disability, etc.).
- Specific conditions of the expense (documentation, payment method, purpose, etc.).
It’s also common for taxpayers to forget to include them or not check if they meet the requirements, which can result in missed savings opportunities.
Main deductions highlighted by category
Housing
Housing remains one of the areas with the largest number of deductions:
- Main residence rent, especially for young people, seniors, or vulnerable groups (notable in communities such as Madrid or Catalonia).
- Purchase or renovation, particularly in rural areas or regions at risk of depopulation.
- Energy efficiency improvements, increasingly incentivized.
- Deductions for property owners who rent homes or mobilize vacant properties.
Family, work-life balance, and education
Many regions prioritize support for families:
- Deductions for birth, adoption, or foster care.
- Benefits for large or single-parent families.
- Expenses for daycare and childcare.
- Deductions for education: textbooks, school supplies, or extracurricular activities such as language or computer courses.
Health, wellness, and new deductible expenses
In recent years, new deductions related to wellness have gained importance:
- Expenses related to specific illnesses (such as celiac disease or rare diseases).
- Gym memberships or sports activities, introduced in several regions.
- Veterinary expenses in certain autonomous communities.
Mobility and sustainability
- Deductions for purchasing electric or plug-in hybrid vehicles.
- Expenses for installing charging points in private or shared housing.
- Investments in energy-efficient home renovations or renewable energy systems.
Depopulation and relocation
Several communities have introduced incentives to attract residents:
- Deductions for moving residence to rural or depopulated areas.
- Benefits for those who purchase or rent a home in these municipalities.
- Additional incentives if the relocation is work-related.
Practical examples by autonomous community
Although each community has its own catalogue, some examples help understand the impact:
- In Madrid, the rent deduction for young people stands out.
- In Catalonia, deductions linked to rent and family situations are also significant.
- In Andalusia or Murcia, newer deductions such as sports or veterinary expenses are included.
- In communities such as Asturias, Cantabria, or Extremadura, measures against depopulation are especially relevant.
- In regions like Aragon or Castile-La Mancha, education and childcare deductions stand out.
How to make the most of deductions
To apply these deductions correctly, taxpayers should:
- Review the specific requirements of their autonomous community.
- Keep invoices, receipts, and proof of payment.
- Consult with tax advisors if in doubt about limits, percentages, or compatibility with other deductions.
We recommend not relying solely on the draft return and taking the time to review these deductions, as they can have a direct impact on the final tax outcome.
